Thc4U's First grow

Hey all, The growth is ridiculous, I would have thought the plants to have grown taller but numbers don't lie, ledd than 10cm growth, The plants are much much busier, the ms reading is also extremely high but I think this has to do with the calsium, for some reason it pushes it way high. Otherwise I dont seem to see any deficiencies, some of the leaves are starting to curl, I'm sure due to nitrogen toxicity. This week we dropped the n to half should fix that. At this point the top growth doesn't seem to have much growth difference between white and black buckets... Other than much stronger roots in the black buckets. I think I am going to work on the lights this week, rise them 20cm and increase output from 800w over 2m squared to 1200 over 2m squared
